I have been wondering if it's worth me experimenting with another kind of antenna for medium wave. As you know, I can't sing enough praises about the flag antenna, but I am pulling my hair out regarding noise.

Yesterday, I moved my flag into different positions and different parts of the garden in a vain attempt to find the direction of my noise. It was not nullable in any direction! This might suggests that the noise could be coming from underground cables, though nothing I do points clearly to anything. The noise is simply everywhere! Perhaps somebody with more knowledge about DFing noise, etc. will be able to find the noise in seconds. I was also wondering if it was my flag is the problem as there's soemthing odd about the tuning of the resistor. But I was able to remove some of the noise yesterday by bypassing the tuning resistor. This somehow cuts the noise down by about 50%. UK/European splatter is immediately worse, but the noise is reduced.

It would also be good to secure an antenna and remove the chances of antennas blowing over in the high winds we get here. This has happened twice this week.

So, I was thinking about building a K9AY. On paper, it looks like the null is similar to that of the flag, plus I understand that it has more gain. Perhaps somebody can correct me if that is wrong. I am a disaster area when it comes to building antennas so I don't want anything too complicated. The only thing which worries me about the K9AY is its height. 25 feet for the central support is too high. I wonder if a K9AY would work if it was slightly reduced in size? I already had the housing officer visit last week asking what on earth 'that wire' was on my garden. (My flag!) She also asked if there was a wire running into the property, to which I answered "Yes". So I am expecting more trouble regarding this.

Any information, tips, advice, help, etc. would be appreciated. Or I am close to giving up medium wave DXing for good, unless my noise magically stops.

I don't think swapping the Flag for a K9AY would help the noise issue. I also don't think underground cables are the culprit as the soil would grossly attenuate the noise. I may be wrong on both counts but on the balance of probabilities...

Where does the noise start and where does it end on the spectrum? Is the noise less in the HF amateur bands? If you replace the Flag with a simple long-wire or sloper is the noise the same? Can you post a sample video of the noise?

If the noise is causing reception on the amateur bands to be badly impacted as a licensed amateur you can raise a case with Ofcom directly. Worst cases are solar panels and/or VDSL - Ofcom will do nothing. Best case is a dodgy power supply which they can try and locate and speak to the owners...I heard about a case this week whereby a herb blanket (new to me as well) battery was pulsing all over HF...Swapping the cheap Chinese ps for a Slab cell cured the issue.

The noise starts at the bottom of medium wave from about 700 kHz. It's solid right up to 10 MHz. I haven't checked above 10 MHz. So amateur bands are affected. Perhaps I should reactivate some kind of amateur radio operation so I can state my case as a practising operator. Do you think that would helop my case is I reported this to OFCOM?

This noise peaks at certain times of the day too. The lengths of the stronger noise bursts vary, as does the duration, but there are three main daily bursts. Midday, late afternoon into early evening and sunrise.

You HAVE to be an amateur to report directly to Ofcom. Get your 7000 set-up with a simple antenna and record the amateur bands. I'm not sure of Ofcom report link but think you can get to it from the RSGB EMC section.

Seems that G.fast profile 1 will use 106 MHz, but in future profile 2 will use 212 MHz. That'll wipe out some people's DAB reception as well. Wasn't that supposed to be the main digital platform going forward?
